Abstract: Title: A Pallet Shelf System Abstract of the Disclosure The invention relates to a pallet shelf system in the form of horizontal I-profiles. The profiles are secured to vertical posts by means of fittings comprising a plate portion of almost the same height as the body portion of the profile. This plate portion com-prises at its lower ridge relatively large projections and at its upper ridge relatively small projections, said projections being disposable in corresponding openings in the flanges of the profile. As a result the profile and the fitting secured to the profile are capable of standing a high torque load.

Abstract: Abstract A radiantly heated furnace is provided with a heating arrangement capable of generating heat from two different sources of energy.  The arrangement includes a thin-walled tube extending within the furnace which operates as a resis-tor when connected to a high current source of electrical energy to generate and radiate heat within the furnace.          The thin-walled tube also acts to radiate heat into the furnace from hot burner gases injected therein by a fuel fired burner.  The arrangement is so constructed that switch-ing from the electric to the gas fire mode or vice versa can be swiftly effected without removal of electrical connections or burners.

Abstract: Abstract of the Disclosure Apparatus is provided to apply pulling forces from any direction from any elevation around a vehicle being repaired and/or serviced.  The apparatus is arranged so personnel using it are concerned with minimal physical lifting movements and minimal setup arrangements of the apparatus.          Each embodiment of the apparatus utilize at least one tower assembly equipped with an elongating subassembly to move a tension member, through directional change devices, as it remains secured to some portion of a vehicle, thereby undergoing at least one repositioning pull in a direction opposite to at least one prior force that previously caused some of the damage and/or misalignment.  Depending on the magnitude of the restoring force required, the tower, other towers,and/or other structures may be secured together and/or to the vehicle as well, to create a firm basis for anchoring the apparatus and/or the vehicle as one or more reactive forces are controllably created.  Depending on the anticipated use of the apparatus and the capital expenditures to be made, the apparatus is made available in different embodiments, ranging from a sole location of a tower to multiple locations of several towers related to overall reactive structures and/or vehicle ramps serving as mutual multiple holding or anchoring places of forces applied to the vehicle, as the elongating subassemblies of the towers are moved to create the restorative pulling forces.

Title: Adhereable elastomer from  moisture-curable silicone compositions
Inventor: BOSCH ERHARD
IPC: C08L83/00
Filed: 1978-08-17
Granted: 1982-05-25
Abstract: ABSTRACT OF THE DISCLOSURE         Curable compositions are provided herein which can be stored under anhydrous conditions, but which when exposed to atmospheric moisture cross-link to form elastomers.  Such compositions consist essentially of diorganopolysiloxane having terminal condensable groups.  The second is a silicon compound containing at least three hydrolyzable groups per molecule, in which the hydrolyzable groups are amino groups bonded to silicon via nitrogen and/or oxime groups bonded to silicon via oxygen.  The third is at least one additional component which improves adhesion of the elastomers obtained from such compositions to substrates.  This third additional com-ponent is an organosilicon compound containing at least one amino group which is bonded to silicon via carbon at least one siloxane-oxygen atom. Such compositions have the improved characteristic of complete deep section curing even in the absence of condensation catalysts.  The elastomers adhere to most substrates e.g. glass, porcelain, ceramics, mortar aluminum, brass, stainless steel, galvanized iron, wood paper, polyvinyl chloride polyestors, polystyrene and polymethylmethacrylate in the absence of customary primers.          Thus, they may be used for sealing joints, in vehicles or in buildings. They are also useful as adhesives or cementing compositions, for the manu-facture of electrical insulators and for coating paper, metals, rocks or textiles.

Abstract: Abstract A thin film foil resistor is disclosed wherein a thin metallic foil is bonded to an insulating substrate  and a circuit path is formed on the foil by photographic artwork-etching techniques.       After the circuit is formed, the structure is subjected to another etching process to reduce the thickness of the foil circuit thereby adjusting the value of the resistor.  Terminal lands of the circuit are electroplated and the connecting leads are soldered to the lands.  The value of the resistor is finally adjusted by use of a laser beam, and the resistor is encapsulated.

Title: Digital generator for producing a  sinewave

IPC: G06F1/02

Granted: 1983-03-08
Abstract: ABSTRACT OF THE DISCLOSURE           The present invention provides a digital genera-tor for producing a sinewave in the form of a succession of digitally encoded samples produced with a sampling period T. The sinewave has an amplitude R and a phase difference .PHI. between two successive samples. The yenerator comprises adding  , multiplying and storage circuits for per-forming the following general algorithm:          Ak+1 = aAk - bBk Bk+1 = bAk - aBk where a = cos.PHI., b = sin.PHI., Ao = R and Bo = 0, k = 0, 1, 2, ... The sinewave is defined at the instant k by the vector sum Ak + jBk = Rejk.PHI., wherein the precise algorithm is the following:               Ak+1 = (aAk - bBk)  (1 - 1/2.epsilon.k+1) Bk+1 = (bAk + aBk)  (1 - 1/2.epsilon.k+1) where .epsilon.k+1 = ? (aAk - bBk)2 + ? (bAk + aBk)2 - 1 As it is impossible for cos2.PHI.+ sin2.PHI. to be exactly equal to unity if calculations are performed with finite precision using an even number base, which has the effect of causing the modulus of a sinewave generated by the general algorithm to tend exponentially to 0 or to ? . The present invention overcomes this by using the above precise algorithm using the correction factor (1 - 1/2.epsilon.k+1) to obtain better approxi-mations Ak+1 and Bk+1 which are stable about the desired amplitude R. Such a generator can be used as a local oscil-lator in a modem for example.
